TI-6067 SEISMIC SOURCE ARRAY FIRING CONTROLLER ABSTRACT OF THE DISCLOSURE There is disclosed apparatus for controlling the precise time of firing of each air gun in an array of air guns employed in marine seismic exploration. For each air gun in the array, the apparatus maintains a record of past measured gun delays, that is the time period expiring between the triggering of an air gun and the time that the gun actually fires. Upon the receipt of a fire command, the apparatus inserts appropriate delays before triggering the individual air guns. In this way the air guns are controlled to fire in a precise predetermined sequence. The air guns may be caused to fire either simultaneously or sequentially so as to exercise effective control over the spectral content and the directionality of the energy generated by the array.
